Defect Monstrous Moonshine
The Monster CFT is a (1+1)d holomorphic CFT with the Monster group global symmetry. The symmetry twisted partition functions exhibit the celebrated Monstrous Moonshine Phenomenon. From a modern point of...

A post-quantum theory of classical gravity?
We consider a consistent theory of classical systems coupled to quantum ones. The dynamics is linear in the density matrix, completely positive and trace-preserving. We apply this to construct a...

A computationally universal phase of quantum matter
We provide the first example of a symmetry protected quantum phase that has universal computational power. Throughout this phase, which lives in spatial dimension two, the ground state is a...

How neutron star mergers can be used to study hadron-quark phase transitions
With the detection of GW170817 we have observed the first multi messenger signal from two merging neutron stars. This signal carried a multitude of information about the underlying equation of...

Mapping class group actions on Hopf algebra lattice models
Hopf algebra lattice models are related to certain topological quantum field theories and give rise to topological invariants of oriented surfaces. Examples are the combinatorial quantisation of Chern-Simons theory and...

Testing quantum theory in space
The satellite is the brainchild of a team of researchers, including Perimeter Associate Faculty member Raymond Laflamme , Perimeter Affiliate researcher Thomas Jennewein , and many collaborators from Perimeter’s sister...
Affiliate member
Affiliate members are faculty at Canadian universities who are invited to be regularly involved in the Institute's research activities. Affiliates are appointed to a three-year term. The goals of the...
Inaugural Wittek Quantum Prize awarded to Perimeter PhD student
Perimeter PhD student Xiu-Zhe (Roger) Luo has won the inaugural Wittek Quantum Prize for Open Source Software. The Quantum Open Source Foundation (QOSF) administers the $4,000 US prize, which is...
